Question

Chem 101 Problem Set 9 Spring 2020 Name 1. For each pair of molecules, circle the molecule that has a larger net dipole moment. If the two molecules in the pair have the same magnitude of dipole moment, circle neither and state that both have the same dipole moment. (a) te) Ö=c=0 src=s 2. Predict the direction that the NET dipole moment would be for the following molecules by sketching an arrow from the central atom in the direction of the net dipole moment. If the molecule has no dipole moment, state that it does not. cºn o=c=s sec=s Huc-c: 3. For each pair of molecules, circle the molecule that has a larger net dipole moment. (a) (b) CEC F al- C C F - C-a C- (c) (d) s=cro: C=C=0: - 4. The odor of cinnamon oil is due to cinnamaldehyde. C.H.O, shown below. What is the hybridization of each carbon atom in cinnamaldehyde? How many sigma and how many pi bonds does cinnamaldehyde have? (a) hybridization: HH 0 Н.С “ сен (b) # of o bonds (c) # of a bonds (d) what is the approximate bond angle around each carbon atom?

Answer 1

== VS 6== © öze=ö Vs š=c=s A Both have some diple moriens Se=s Ü- It does not have dipde moment

Ji S=CES CSS SH. Hirille ..It does not have dipole moment I 3 - C - B zo .. vs Seco

@ hybridization of each cartoon = sp- B # of o bonds 18. © # of: tf bonds = 5 @ The opprexinate bond angle around each carbon atom. 1200
